Any deviation from that for faster warmup is extra fuel used.* My car has lived 200,000 miles, so I doubt extra wear is a significant factor.
Faster warmup does mean lower fuel usage later in the trip, but at best you get back half of what you spent warming up. Best fuel consumption is to arrive at the other end with the coldest engine you can. Grille block to make it warm up faster.

I agree with PaleMelanesian on his approach.
I drive in New England, where we get winters.
I use EOC as much as possible on a cold engine. Grill block helps a lot. I use my ScanGauge to indicate engine temp, and that tells me whether I have too much or too little grill block for that day's temperatures. I wear a warm jacket in winter, partially because I don't heat my car like a sauna, and it can take some time to warm up.
